Abstract

Remote control actuators for endoscopic tools are provided. Each remote control actuator includes a driver, a coupler which couple the endoscopic tool to the driver, a power source which power the driver, and a controller coupled to the power source and/or the driver for controlling the power applied to the driver. In conjunction with the controller, a user interface is preferably provided for user control of the remote control actuator which actuates the endoscopic tool. In addition, a sensing/feedback mechanism is preferably provided between the driver and the endoscopic tool and is coupled to the controller and/or the power source. The sensing/feedback mechanism senses the amount of tension or compression on the pull wire(s) of the endoscopic tool and provides a related signal to the controller so that the force applied to the endoscopic tool may be regulated. Various types of power sources are disclosed including electric, mechanical, hydraulic, and pneumatic. Various types of drivers are disclosed, including a motor/linear actuator, a hydraulic or pneumatic piston, and a motor with or without reduction gears coupled to a pulley and belt or a sprocket and chain or a rack and pinion. In addition, several couplers, controllers, user interfaces, and sensing/feedback mechanisms are disclosed.
